Testicular sperm extraction (TESE)

If no sperm can be detected in the male ejaculate (azoospermia), in some cases it is possible to obtain sperm cells by means of a testicular biopsy (TESE).
TESE stands for “testicular sperm extraction.” In this procedure, tissue is removed from the testicle and examined for the presence of sperm cells.

These are outpatient procedures that are routinely performed at the Dr. Loimer Fertility Institute by a urology specialist under light sedation.
Any sperm cells found can then be stored at -196°C in liquid nitrogen at KIWI.

If sperm is obtained using TESE, ICSI (intracytoplasmic sperm injection) is required for subsequent fertility treatment.
